iOS 26.6 SAVED my iPhone 13 Pro with 82% battery after 26.5 ruined it
My story:
I was running iOS 26 on my iPhone 13 Pro 256GB (82% battery health) — and it was perfect: smooth UI, solid battery life, zero overheating. Thought "newer = better" and jumped to iOS 26.5.
First 2 weeks of pain:
· Phone overheated on basic tasks (YouTube, social media, even just scrolling).
· Lost LTE connection a couple of times — network just died and wouldn't come back.
· The buttery-smooth experience was gone. Micro-stutters everywhere, phone felt sluggish and strained.
I told myself: "Maybe I'll get used to it." Nope. Didn't happen. It was the end of my comfortable iPhone experience.

How I saved it:
Took a risk and updated to iOS 26.6. First couple of days — same heat issues. That was Spotlight indexing and background services. I held on.
Results after 2-3 days:
· 🔥 Overheating gone — phone stays cool even under load.
· 🔋 Battery life almost back to iOS 26.0 levels (the good old days).
· 📶 LTE rock solid — no drops since.
· ⚡ UI smoothness 100% restored — no stutters, no lag.

My verdict:
iOS 26.6 resurrected my iPhone 13 Pro. If you're suffering on 26.5 — don't wait, update. If you're still on 26.0 — I'm not sure if you should even bother, but 26.6 is definitely not worse than what you have.
No idea what iOS 27 will bring, but for now — I saved my comfort.

Question for y'all:
Anyone else on 13 Pro with 80-85% battery health? How's 26.6 treating you? Or maybe someone's already on the 27 beta — worth jumping or wait it out?

P.S. This one's for everyone who fears every update because their phone is "not that young anymore."
